Sixty-eight patients had LRV entrapment, while 58 of them (58/68) were diagnosed with OP. Sixty-four patients had elevated micro-proteinuria after activity while 58 of them (58/64) were diagnosed with OP. In the presence of both parametrs, 61 patients had both LRV entrapment and elevated micro-proteinuria after activity, and 56/61 were diagnosed with OP. The Se, Sp, PPV, NPV, PLR (W), NLR (W) and YI for combined use of two parameters were 93.3% (95% CI: 0.83–0.98), 66.7% (95% CI: 0.39–0.87), 91.8% (95% CI: 0.81–0.97), 71.4% (95% CI: 0.42–0.90), 11.2 (95% CI: 4.82–26.00), 0.40 (95% CI: 0.17–0.97) and 60%, respectively. LRV, left renal vein; OP, orthostatic proteinuria; Se, sensitivity; Sp, specificity; PPV, positive predictive values; NPV, negative predictive values; PLR (W), positive likelihood ratios (weighted by prevalence); NLR (W), negative likelihood ratios (weighted by prevalence); YI, Youden’s index.
